Misfire Codes & Rough Idle

[culthero]

Decided to start a new thread since the other had gone way too long.

I've got the following codes:
P0313
P0300
P1353
P1351
P0171
P0313p
P0300P

I have a very rough idle, but only when I let it idle for an extended period of time (ie at a traffic light). If I never let it idle normal, say at ever traffic light I put it in Neutral and rev RPMs to 1000...it will never start to idle rough. And if I turn it off while it idle rough, then turn it back on, the rough idle goes away until I let it sit for a while again.

I've already put new spark plugs, checked for vacuum leaks on hoses, cleaned out DISA vavle, cleaned out Idle Ctrl Valve, and swapped coils cleared the codes and the codes came back with a misfire on the same cylinders.

If I put a bottle of Lucas Fuel Injector Cleaner it runs better and I can actually sit at a traffic light without the rough idle. It takes a lot longer to start the rough idle.

Anyone have any ideas....bad injector or bad O2 sensor maybe?
